Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129346, here are decompositions:
- 5 + 129341 = 129346
- 53 + 129293 = 129346
- 59 + 129287 = 129346
- 83 + 129263 = 129346
- 137 + 129209 = 129346
- 149 + 129197 = 129346
- 227 + 129119 = 129346
- 233 + 129113 = 129346
Showing the first eight; more decompositions exist.
